Shock find brings extinct mouse back from the dead

Researchers have successfully resurrected the extinct Gould's mouse, a significant finding given the high rate of native rodent extinction in Australia. The study revealed that the species' genetic diversity did not guarantee its survival, underscoring the rapid decline of populations in the face of invasive species, habitat destructio...

Transforming the layered ferromagnet F5GT for future spintronics

A RMIT-led international collaboration has achieved record-high electron doping in a layered ferromagnet, causing magnetic phase transition with significant promise for future electronics. Ultra-high-charge, doping-induced magnetic phase transition in Fe5Ge2 enables promising applications in antiferromagnetic spintronic devices.

A novel method for controlling the microstructure and performance of 3D printed human implants

Researchers propose a triple-cycle heat treatment system to improve the microstructure and performance of 3D printed titanium-molybdenum alloy human implants, achieving better biocompatibility and mechanical properties matching human bones. This method enables more widespread use of 3D printed implants in the biomedical field.

Males help keep populations genetically healthy

A new study from Uppsala University reveals that males play a crucial role in maintaining genetic health by eliminating harmful mutations. The research found that selective pressure on males leads to the purging of deleterious mutations, resulting in healthier genes and increased reproductive capacity.

Toxicity of protein involved in Alzheimer's triggered by a chemical 'switch'

Researchers at Tokyo Metropolitan University have discovered that disulfide bonds on certain amino acids stabilize tau protein, leading to its accumulation and triggering neurodegenerative diseases like Alzheimer's. The study suggests that targeting these chemical groups may lead to novel treatments to reduce or prevent tau accumulation.

Smart transfer rules can strengthen EU climate policy

The study suggests that revenues from emissions pricing should be distributed according to historical emissions, providing the greatest leeway for a consensual ambitious climate policy. This design can help overcome obstacles such as differing country sizes and wealth, ultimately strengthening EU climate policy.
